Grammy-nominated singer and actress Demi Lovato rose to fame in her teens, making her first gold record in 2008. Now 25, the chart-topping artist says her road to success wasn’t easy, and that she battled addiction, eating disorders, bipolar disorder, and self-harm for years.

Now six years sober, Demi is a partner at CAST Centers, a treatment and comprehensive wellness program based in West Hollywood, California.

“I actually went to CAST as a client. And I went there because I had a bad shroom trip,” Demi tells Dr. Phil. She says she moved into sober living at CAST, staying for over a year.

Then, the star says she partnered with Mike Bayer, Founder and CEO of CAST. Together they created CASTonTOUR combining concert performances with motivational speakers and the messaging of the CAST Centers, “And it's really been received really well. People have said that it’s changed their lives; that they've learned so much.”

Dr. Phil was a guest speaker at a recent CASTonTOUR event. On Tuesday’s episode, he sits down backstage to speak with Demi and Mike just before the concert.

“My addiction with drugs and alcohol was very severe to where I had several scares, and I knew that at the rate I was using and drinking, I wasn't going to live a long life,” Demi says, adding, “I used very fast, very hard.”
